Pass -Wno-deprecated-copy only for C++, gcc gives a warning for C.
Pass -Wno-unused-command-line-argument for clang only, gcc gives a
warning about it.
Add a failsafe for gcc/clang static link flags if libstdc++ or
libpthread is not available as a static library.
Move link command adjustment script invocations to src/wx, the target is
not yet defined in the toolchain.
Add -lws2_32 to the end of the link command for gcc on Windows because
of link order issues with those symbols.
Disable LTO for gcc on Windows, as it is broken.
Don't install extra-cmake-modules on MINGW32, that package is not
available there.
